Y. 2011 2012 Introduction Manual systems in libraries were used in the 1970s and early 1980s until computers became more prevalent and less costly. Manual systems tended to operate with a card index to monitor the books that borrowers had out. Libraries also used a manual card catalog system for indexing and tracking books. Manual operating systems are vulnerable to human error. For instance, a librarian who misfiles a borrowers records or indexes a book incorrectly slows down the process and wastes employees time. Manual systems are also slow to operate. Instead of using a computer to issue and take back books, locating and updating a card index is slow and laborious. Manual systems are unable to store large amounts of data efficiently. With manual systems staff spends a lot of their time on mechanical, clerical tasks rather than liaising with library visitors.
